--- What is AppArmor? --- AppArmor is MAC style security extension for the Linux kernel. It implements a task centered policy, with task "profiles" being created and loaded from user space. Tasks on the system that do not have a profile defined for them run in an unconfined state which is equivalent to standard Linux DAC permissions. --- How to enable/disable --- set CONFIG_SECURITY_APPARMOR=y If AppArmor should be selected as the default security module then set CONFIG_DEFAULT_SECURITY="apparmor" and CONFIG_SECURITY_APPARMOR_BOOTPARAM_VALUE=1 Build the kernel If AppArmor is not the default security module it can be enabled by passing security=apparmor on the kernel's command line. If AppArmor is the default security module it can be disabled by passing apparmor=0, security=XXXX (where XXX is valid security module), on the kernel's command line For AppArmor to enforce any restrictions beyond standard Linux DAC permissions policy must be loaded into the kernel from user space (see the Documentation and tools links). --- Documentation --- Documentation can be found on the wiki. --- Links --- Mailing List - apparmor@lists.ubuntu.com Wiki - http://apparmor.wiki.kernel.org/ User space tools - https://launchpad.net/apparmor Kernel module - git://git.kernel.org/pub/scm/linux/kernel/git/jj/apparmor-dev.git
